Background: The lengthy period of external fixation for bone consolidation increases the risk of complications during distraction osteogenesis (DO). Both pro-angiogenic and osteogenic potential of bone marrow mesenchymal stem cells (BMSCs) contribute to bone regeneration during DO. The underlying mechanism of Schwann cells (SCs) in promoting bone regeneration during DO remains poorly understood. ⋯ Furthermore, RSC-96 derived CM accelerated bone regeneration, resulting in improved biomechanical parameters, radiological features and histological manifestations, along with increased vascularization in the distraction area. Conclusion: Through activation of AKT/GSK-3β/β-catenin signaling, SCs enhanced the coupled angio- and osteogenesis effects of BMSCs. The preclinical evidence demonstrates that SCs derived CM with increased neurotrophins secretion can be a promising treatment approach to accelerate bone regeneration in the DO process.

Investigating the Process of Autoimmune Inner Ear Disease: Unveiling the Intricacies of Pathogenesis and Therapeutic Strategies.
Autoimmune inner ear disease (AIED) is a rare condition characterized by immune-mediated damage to the inner ear, leading to progressive sensorineural hearing loss (SNHL) and vestibular symptoms such as vertigo and tinnitus. This study investigates the pathogenesis and therapeutic strategies for AIED through the analysis of three cases with different underlying autoimmune disorders: rheumatoid arthritis, relapsing polychondritis, and IgG4-related disease. The etiology of AIED involves complex immunopathological mechanisms, including molecular mimicry and the "bystander effect," with specific autoantibodies, such as those against heat shock protein 70 (HSP70), playing a potential role in cochlear damage. ⋯ Early intervention is crucial for favorable outcomes, as demonstrated in the studied cases, where timely corticosteroid and immunosuppressive treatments led to significant hearing improvement. The study underscores the importance of personalized treatment strategies based on individual immunologic profiles and comorbidities. Our findings highlight the heterogeneity of AIED and the potential for biologic therapies in refractory cases.

Background: Worldwide, approximately 1.7 billion people are afflicted with musculoskeletal (MSK) diseases, posing significant health challenges. The introduction of single-cell RNA sequencing (scRNA-seq) technology provides novel insights and approaches to comprehend the onset, progression, and treatment of MSK diseases. Nevertheless, there is a remarkable lack of analytical and descriptive studies regarding the trajectory, essential research directions, current research situation, pivotal research focuses, and upcoming perspectives. ⋯ Frontiers in Immunology published the greatest number of research papers in this field. This study identified joint diseases, bone neoplasms, bone fractures, and intervertebral disc degeneration as the main research focuses. Conclusion: This extensive scientometric analysis provides substantial benefits to both experienced and novice researchers by facilitating immediate access to critical data, thereby fostering innovation within this field.

Coronary microembolization (CME) is defined as atherosclerotic plaque erosion, spontaneous rupture, or rupture of the plaque while undergoing interventional therapy resulting in the formation of tiny emboli that obstruct the coronary microcirculatory system. For percutaneous coronary intervention, CME is a major complication, with a periprocedural incidence of up to 25%. ⋯ The aim of this review is to summarize the currently known molecular mechanisms underlying CME. Further investigations of the RCD mechanisms may unravel new avenues for the prevention and treatment of CME.

Aminoglycosides and cisplatin drugs are extensively utilized for their high efficacy in treating various conditions in the clinic, however, their ototoxic side effects warrant significant attention. These drugs could penetrate the inner ear via specific channels or transporters, which not only affect the survival of hair cells but also induce the overproduction of reactive oxygen species. Currently, scientific research mainly addresses this issue through the downstream intervention of reactive oxygen species. ⋯ It is, therefore, imperative to investigate the regulatory role of the MET channel in the up-taking of ototoxic drugs, serving as a pivotal point for the development of preventative and therapeutic approaches. This review aims to highlight the mechanism of inhibition of ototoxic substances absorption by auditory hair cells, explore how to develop novel ear protection methods by targeting these channels and transporters, and provide a new perspective and strategy for addressing drug-induced ototoxicity. The approach to protecting hair cells by targeting these channels and transporters not only broadens our understanding of the underlying mechanisms of ototoxicity, but could also spur further research and progress in the field of auditory protection.
